Heard of the Davis Angels Network, or Silicon Valley Bank? The former is working to build a local culture that supports and invests in start-up companies in Davis, and the latter was founded in 1982 to become a major source of funding for emerging tech companies in the Silicon Valley (and grew into an international bank). On today’s Davisville, Lonnie Bookbinder of the Davis Angels, and retired SV Bank chairman Bob Medearis, who both live in Davis, talk about the real efforts to place more start-up ventures in town. There’s more going on in this area in Davis than you might know about.
